The EINVAL for a descriptor without a vnode now applies only to a pipe or socket. A character device is a vnode on FreeBSD, so getvnode succeeds and change_dir fails with ENOTDIR; File::IsCharacterDevice keeps that answer for the host character devices (a tty, NUL or /dev/null) and the guest random device. guest_kernel_sys pins it with /dev/random.

sosend_generic fails a send on a socket that can send no more with EPIPE
before it looks at so_error. Winsock reports the same send as WSAECONNABORTED
or WSAECONNRESET, which reached the guest as ECONNABORTED or ECONNRESET.
A stream send now maps both to EPIPE. The send-after-close checks of
guest_tcp, guest_socket_read_write and guest_socket_pair run on Windows too.

NpTrophy reads the trophy count and icons from the title's trophy
package (names are encrypted and stay not implemented), PS4 v1 save data
calls wrap the native v2/v3 ones, and NpWebApi library contexts, handles
and push event filters work offline (service filters fail without a
signed-in user). libSceAjm is built from the libSceAjm.native sources
for PS4 titles. Limbo's (CUSA01664) remaining PS4 imports, including the
synchronous PS4 TUS calls and the Facebook dialog calls next to the
existing libraries, are exported as not implemented.
FreeBSD 11.4's vn_seek fails SEEK_CUR and SEEK_END with EOVERFLOW when the base offset plus a positive offset does not fit in an off_t, and with EINVAL only when the result is negative. The host lseek reports EINVAL for the overflow, so the guest saw EINVAL. When the host call fails with EINVAL for a positive offset on SEEK_CUR or SEEK_END, the base position is read back and the call fails with EOVERFLOW if the sum would overflow; the file position is left unchanged.

On Linux the host keeps data that was buffered before shutdown(SHUT_RD) and
guest_socket_pair expects to read it, so the shortcut that answers 0 for any
receive after SHUT_RD broke that test there. Limit the shortcut to Windows,
where the host cannot answer it, and run the post-shutdown receives of
guest_tcp on Windows only.

soreceive_generic returns 0 for a socket whose receive side is shut and for a
zero-length receive on a connected stream socket (ENOTCONN when it is not
connected), without waiting. Winsock fails the first with WSAESHUTDOWN, which
reached the guest as EPIPE, and blocks the second until data arrives. recv and
recvfrom now answer both themselves.

On Linux sceKernelGetdirentries copied the host d_type, so a directory under app0 that is a host symlink was listed as a link, and a title that only descends into directory entries skipped it. Inside the app0 tree, report a symlink (or an entry of unknown type) as the type of its target; links elsewhere, and dangling links, stay links.
WSAPoll reports POLLHUP alone for a stream socket whose peer has closed, so
poll never returned POLLIN for it and a caller waiting for POLLIN did not see
the end of the stream. sopoll_generic reports a socket that can receive no
more as readable and adds POLLHUP only once it can send no more either.
poll now adds the requested read bit and keeps POLLHUP only after the socket
shut its own sending side. A reset or refused connection keeps WSAPoll's flags.

FreeBSD 11 fopen opens the path with _open, and vn_open_vnode refuses a
directory only for FWRITE or O_TRUNC, so fopen of a directory in a read
mode succeeds; Linux hosts already open it. On Windows CreateFileW
without FILE_FLAG_BACKUP_SEMANTICS refused it with EACCES.
fopen now opens such a path as a libkernel directory descriptor, which
libkernel registers in libc when it loads, and fclose and freopen remove
it from libkernel's table. Reads on the stream fail with EISDIR and set
the error indicator, as on a Linux host and FreeBSD's tmpfs: the Windows
CRT fails them already but reports EINVAL. Writes fail with EBADF, and
fseek, ftell and ungetc work, as on any read-only stream.
